Nau, known for their eco-friendly clothing and sleek styles, currently has a great billfold in their collection. Apparently we’re not the only ones feeling it too, their lead designer recently mentioned it in his top 5 picks. The simplified wallet features a herringbone shell which looks great and separates it from most styles on the market, and is crafted with a pocket-friendly slim profile. The billfold has a cash sleeve, six card pockets to hold everything you need, and even a sim card slot– though we’re not sure why you’ll need that. It’s available for only $35 at Nau.
